3. Installation Instructions
3.1 Pre-Installation
- Ensure the air supply is maintained pristine, devoid of moisture, oil, or any contaminants for an optimal setup.
- Validate the compatibility of the valve model with the existing machine's pneumatic interfaces for seamless integration.
3.2 Installation Procedure
1. Mounting: Affix the valve vertically in its precise location on the press pneumatic control panel using M6 bolts to guarantee a stable and enduring installation.
2. Pneumatic Connections:
- Main Circuit: Attach the air supply to the inlet (P) and ensure the actuator, such as a cylinder, connects smoothly to the outlet (A).
- Redundant Circuit: Connect the backup channel independently to eliminate any cross-interference, fortifying system integrity.
3. Electrical Wiring:
- Solenoid Coil Voltage: Designed for compatibility with DC24V±10% or 110V/220V; specify voltage priorly. Ensure a correct polarity configuration with the red wire as positive and the black as negative for impeccable operation.
- Properly ground the wire to the equipment's earthing terminal, securing maximum safety standards.
4. Operating Procedures
4.1 Pre-Operation Checks
- Confirm the manual reset button is in the "ON" position to initiate operations safely.
- Activate the test button to simulate an emergency stop, ensuring the dual channels respond with flawless synchronization.
4.2 Normal Operation
- During standard operations, both valves function collectively. If a channel fails, a red alert light is activated, seamlessly switching to the backup system to maintain uninterrupted operational performance.
4.3 Emergency Stop
- Press the E-stop button to immediately cut off the air supply, causing the press slide to halt instantly, thus ensuring top-tier safety.

5. Maintenance
5.1 Routine Maintenance
- Perform weekly cleaning of the valve surface and meticulously inspect air hose connections for any potential leaks.
- Conduct a monthly assessment of the response time to ensure optimal functionality; record data accurately for thorough maintenance.
5.2 Periodic Service
- Ensure the longevity of your valve by replacing seals every six months and meticulously cleansing the spool with anhydrous ethanol, ensuring optimal performance and durability.
- To maintain peak performance, arrange for a professional to calibrate the solenoids and sensors annually, ensuring they function with precision and efficiency.
6. Troubleshooting
Symptom Possible Cause Solution
Valve Inaction: If facing power issues or coil burnout, verify the wiring thoroughly and replace the coil if necessary to restore seamless operation.
Air Leakage: Experiencing issues with seal degradation or loose fittings? Secure reliable operation by promptly replacing seals or tightening fittings.
Delayed Response: If you encounter low pressure or spool blockage, enhance operational efficiency by increasing pressure or cleaning the spool for responsive performance.
7. Safety Warnings
- 1. NEVER attempt to disassemble the valve while it's under pressure! Always ensure the entire system is completely depressurized before maintenance to guarantee your safety and system integrity.
- 2. Internal adjustments are strictly for authorized personnel only, preserving the system's integrity and ensuring safety from unauthorized tampering.
- 3. Immediately halt operations if you detect any abnormal noise or leakage to prevent potential damage or safety hazards.
